<span>Bob can buy a cake that costs 13.50 Pounds and serves 12 people. It means that he needs 5 cakes of that type ( 5 * 12 = 60 > 57, so everyone gets a slice ). It would cost totally: 5 * 13.50 = 67.50 Pounds. Another cake that Bob can buy costs 18.75 Pounds and it serves 20 people. Now he would need 3 cakes ( 3 * 20 = 60 > 57 ). So 3 * 18.75 = 56.25 Pounds. And because Bob wants to pay as little as possible for the cakes, he would choose the 2nd cake. Answer: Bob will have to pay 56.25 Pounds. </span>

Answer:
C 44.59
Step-by-step explanation:
The first two shirts are full price
2*49.96 = 99.92
The third shirt is 50% off. That means it is 50% of the original price
.5*49.96 = 24.98
The total cost before tax is
99.92+24.98 =124.90
tax = cost * tax rate
tax = 124.90*.071
tax=8.87
Add this to the cost
final cost = 124.90+8.87
=133.77
We want to find the mean cost (average cost)
Take the total cost and divide by the number of shirts
133.77/3 =44.59
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66
